The question of what is the “best” moral system isn’t the same as what is a good moral system. Morality is the way people actually are regarding behavior. One may direct society to select various behaviors through sundry means to accomplish various purposes. Yet rather than being moral relativism this view of morality is descriptive rather than prescriptive. Sociology 101 brings up agents of socialization and how laws arise from folkways etc
There were people like Mill and Locke that created moral systems by design such as utilitarianism. Yet most moral packages are less than complete, much less efficient, and their comparative values are set and determined at least in part upon the basis of one’s opinions about life and its meaning. I believe that Christ was/is true and that original sin, contained in the thermodynamic parameters of the decohered state of quantum entanglement in the Higgs field of massless two dimensional particles, is part of the penalty or necessary reduction from a state of eternal bliss due to original sin.
Harlan Ellison’s ‘I Have no Mouth and I Must Scream’ was a science fiction story that partly distilled and reduced to a pure state the fallen fate of humanity contained in the nature of thermodynamics with metaphor and in that particular scenario- an A.I. An AI tortured the last 5 human survivors within its physically, relatively omnipowerful command of quantum mechanics. The good can only be found with God through the grace of His Son.
Besides that, in the field dynamics of sin and biology people are embedded in a kind of Skinnerian stim/response relationship driven by sex and food- though the ways of viewing that are complex. A more intellectual and spiritual approach being reborn with an objective sense of the problems inherent does exist for the saved.
Some are content with Quantum mysticism and lack faith. Others are nihilists and some radical subjectivists metaphysically make the objective interpretation of wave-form collapse error. They believe they create reality by viewing it. Within the multivarious possibilities for human behavior the criterion of values leads choices for moral outlook. Of course many moral structures are socially inherited. People like Nietzsche regarded that as ossified moral praxis. He preferred to be ‘Beyond Good and Evil’ yet that was an inference from his metaphysics of eternal recurrence. In effect those recurring eternally unaware were like objects rather than human piers to those that were woke. It rendered personal egoism into personal sociopathy. Nazis loved the philosophy.
I believe humanity falls short of designing flawless, airtight logical systems that work. So long as life is temporal and limited, those error prone systems are not transcendingly important. They are contained by mortality and do not extend into eternity except perhaps for one critical choice.
